One of the first concerts I went to as a kid(13 yrs old) was ELO's "Out Of The Blue" tour at Anaheim stadium in 1978. The stage was a giant lighting-laden recreation of the spaceship on the album that hydraulically opened to reveal the band complete with a Laserium laser light show. Mind-blowing at the time, but pretty cheesy now in hindsight.
Here's a great account of the tour technical details
